Hi All,
I too found water under my holding tank but it was not draining into the bilge. Turns out it was the hot water service leaking into the area under the sink and running across the hull to under the holding tank. I suggest you check all of your fresh water lines and tanks for leaks. I have also had failures of the push-on fittings but these were on the pressure side of the pump.

If you pumped the h. tank reasonably empty at 10, it can't be tank ? (My h. tank developed a hole several years ago and I had to replace it - the lower, forward, port corner had abraded against the hull due to small movement over years. (boat is 1999) It was obviously the tank, as the holding tank contents are literally 'black water' and smell. Cleaning and disinfecting the bilge was a task. Fortunately for you, it doesn't sound like that to me.)
Given the 'path of water' you are seeing, I'd suspect something in the head under the sink - maybe the thru hull there (raw water intake, or sink drain). Water under the head floor can path forward and appear to be coming under the holding tank.

So can leaks from under the galley sink area. The path a leak will take often times is indirect and can be a head scratcher.

Hey All!
Had some excitement on Sunday morning, on the hook in Still Pond!I got up first to start the tea pot on the stove in the galley.(My wife was still snoozing a bit...)?As I usually do, I ventured outinto the cockpit and turned the LP tank on... instead of the normal 1/4 second "psst" of the?gas bottle charging the gauge up to pressure, I (we actually) heard a POP! and the gas bottle?continued to "pssssssssssss..."! I immediately turned the valve off and headed into the cabin.There was a heavy oder of gas in the galley area. Needless to say, no stove valves were left on.The I realized that I hadn't switched the gas solenoid switch on, so I was amazed that gas made it into the cabin!
Some friends that I've been talking with think that the pressure regulator failed and the gas valve solenoid?(down stream of the regulator) was a low pressure solenoid and couldn't take the pressure (which was?about 30 psi at the time, if you could believe the gauge).
I can't help thinking that if I would have got a burner started and *then* the system failed with the burner lit,?it coulda been really BAD! Especially since my wife was in the aft cabin and couldn't egress very quickly!I think my first reaction would've been to go to the control panel to turn the solenoid switch off,?loosing precious time getting to the bottle valve.
So I was wondering:
-Anyone else have this happen to them?-Could the Stove be damaged after getting a jolt of hi-pressure gas? (obviously *something* leaked in the cabin)-Since I'm gonna replace the tank (it's? a '97 original), regulator and solenoid,?should I also pull a new gas line or just pressure check it? It seems pretty involved to fish a new one?but probably a good thing to do?-How would I pressure check the stove components? Is there recommended pressure to set and monitor for leaks in the stove's components?-Am I technically allowed to do this work myself without certification?
I'm a pretty capable mechanic and have run and repaired gas lines in my home, so I'm not against doing the work myself.I can imagine the yard would charge me an arm and a leg to diagnose and repair the system before they were done.

I hope that it moves on out. The one time we had damage was a cat one that stalled right on top of us for a whole day and broke the weld on the 5/16 stainless mooring ring. Have a 1? galvanized steel shackle on it this time.

You don't say where the "pop" noise came from.? Your friends' theory seems to require multiple failures: the pressure regulator, followed by the solenoid, followed by something in the cabin (otherwise it seems unlikely you would have had gas in the cabin).
In any event, I'm glad it wasn't more serious. The news today about the dive boat fire in California is sobering.

I suspect that your gas line may have come off or ruptured in your cabin. Not sure why, but having run sever lines from the saloon to the aft lockers, I can suggest that the only thing tricky about it would be sealing it at the locker?

Here in Australia we now need a gas two stage regulator for caravans, boats,
etc. I believe the Catalinas used to come with a single stage one.
Apparently the two stage regulators are safer as they are less likely to
suffer complete failure.
My understanding is that the gas line in the boat is a flexible one. Given
that it is now 22 years old it really should be replaced. There well could be
insurance implications in the event of a loss due to failure of an old
flexible gas line. Also in Australia you would not get a gas certificate for
such an old flexible line and you can't sell the boat without a gas
certificate. Finally our local regulations also require all gas work to be
done by a licensed gas fitter. Your local situation may be different but given
that you have already experienced a failure . . .

I was thinking about this problem on the way back to HdG yesterday.
Although I'm not a huge fan of multiple cascading failure theories, in this
case it really does seem to be the only logical answer, and I was able to
piece together a couple more clues for you.
1) According to CD, the old solenoid was rated for 15 lbs. Although it
isn?t clear what happens beyond that rating, the fact that the old spec is
silent on what happens with a high pressure failure mode is indicative that
perhaps older solenoids did not address this issue.
2) According to Defender, their newer solenoids all state that they will
not open if pressure is ?too high?. CD remains silent on their ?drop in
replacement?
3) Regulators should be replaced every 10-15 years or so. Here is some
interesting language from CD. ? Older regulators may be potentially
hazardous, so if your regulator is more than 15 years old, please don't
take a chance and hope for the best by not replacing it!?.
*4. *Apparently hoses also degrade over time. 15-20 years seems to be
warranted life.
Here?s a article form west marine on the topic.
https://urldefense.proofpoint.com/v2/url?u=https-3A__www.westmarine.com_WestAdvisor_Safe-2DPropane-2DInstallations&d=DwICAg&c=3gr2qZ7ZEvzGFhHLB8UWaw&r=UclYbmpxKKMdPPqgh30Tnw&m=UO5NIq9ZzESNPpWSQrhlJw8hDE_pO0YrOb7i5j-2dPY&s=k11nS8ZagDR9dNyEJWdUXMpJKL7od6PRAgTvFYhuFyE&e=
I would probably do this install myself. Is it possible to do the work
yourself and pay the yard to check for leaks? There aren?t that many
connections and you can leak check them all the same way you would at home
but I get the value of a second opinion when there is gas involved.
Good luck
Troy

We were anchored next to Conception in Prisoners Harbor on Santa Cruz Island 2 days before the accident. A friend of ours is one of the Captains but was not on the boat at the time . I will be replacing the pressure regulator and solenoid as soon as possible as a preventative measure.

I always only manually turn the gas valve on with my wife at the stove starting it.

The solenoid may not have failed at all. I think the type we have is sprung shut and the solenoid works against the spring so that they fail safe on power loss. It isn?t a rotational motion of a valve like more sophisticated valves.
So if unregulated pressurised gas works against the spring it will easily overcome it.
Before you replace the solenoid therefore, fit a new regulator and retest it.
Downstream of the solenoid it is then a matter of finding whether a hose burst or if a valve or joint failed under pressure.
Here in the UK we now have to fit regulators that fail safe by venting to atmosphere if the regulator fails. Not quite sure how they work!
